GIDEON B. MASSEY, OF MOUNT VERNON, NEV YORK.

CAR-WINDOW SHADE.

SPECIFICATION forming part of Letters Patent No. 311,906, dated February10, 1885.

Application filed April 8, 1884.

To all whom t may concern:

Be it known that I, GIDEON B. MAssEY, of Mount Vernon, in the county ofWestchester and State of New York, have invented a new and ImprovedCar-Window Shade, oi'which the following is afull,clear,and exactdescription. Y

The object of my invention is to provide certain new and usefulimprovements in car- 'window shades whereby the said shades can be heldeasily in any desired position.

The invention consists in the combination, with a shade-roller and ashade secured to the same, ot' a vertically-slotted guide-standard, intothe slots of which the ends of a strip secured on the free end of thecurtain pass. Cords or wires are secured to the corresponding ends ofthestrip and roller, and pass over suitable pulleys.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a face view of part ot a car-window shade provided with myimprovement. Fig. 2 is an end View ofthe same, and a side view of theguide-strip for the shade. Fig. 3 is a side view of the strip,showing amodified construction.

The shade A is secured on a roller. B, journaled in the upper ends ofstandards C, the ends D ot` the roller projecting through the standard.

To the bottom edge ofthe shade a strip, E, is secured, the ends of whichpass through vertical guide-slots I in the standards.

To each projecting end of the strip E a cord, F, is fastened, whichpasses over a grooved pulley, G, pivoted on the outer surface ot' thecorresponding standard.G, at the bottom ofthe saine, and which cord Fhas its opposite end secured to the corresponding projecting end oftheroller B.'

If the shade is pulled down, the cords F are Wound on the projectingends D ot the roller B, and if the shade is raised and the strip E ispulled up the cords F are unwound from the ends D of the roller A. Thefriction of the cord on the ends of the roller and on the pulley G issufficient to hold the shade in place. The ends D of the shade-rollerareV tapered, so that the tension of the cords F will remain uniform,for, as the diameter of the roller increases as more of the shade iswound (No model.)

on it, the end of the roller must be beveled,

.so that more ot' the cord will be wound on the roller as rapidly as theshade is unwound, and, vice versa, as the shade is Wound on the rollerand the same increases in thickness, a comparatively smaller quantityofthe cord must be unwound from the roller.

In place of the cords F, chains H may be used, which have their endssecured to the.

top and bottom edges of the projecting ends ofthe strip E, and thesechains are passed over pulleys J on the ends ot' the roller, and thepulleys G on the bottoms of the standards O. The pulleys .I are groovedor formed as sprocket-wheels.A A brake-spring, K, rests against theroller, and is provided with an adjusting-screw, L, by means of whichbrakeshoe the friction on the roller can be adjusted as desired to holdthe shade at any desired height. In place of the cords F, wire cables orwires may be used. @oiled-Wire belting can be used in place ofthe cord For chain H, which belting is secured to the bottom strip ofthe curtainand to the roller, or is passed around the pulley on the roller and thebottom pulley. lf the coiled-wire belting` is used, no compensatingdevice need be provided, as the wire belting stretches sufficiently tocompensate for the number of windings around the end of the roller.

Having thus described my inventio n.Iclaim as new and desire to secureby Letters Patentl. The combinatiomwith a shade-roller having taperedends, and a shade secured on the said roller,of the standards C, havingvertical guide-grooves I, the strip E, secured to the bottom ofthecurtain and having its ends passed through the slots I, the pulleys G-at the lower ends ofthe standards, and the cords F, secured to the endsof the roller and to the ends ot' the strip E, substantially as hereinshownand described.

2. The combination, with a shade-roller and a shade secured to the same,of a vertically-slotted standard, a strip secured to the shade andprojecting through the vertical slots of the standards, and of cords orropes secured to the rollers and to the said strip and passing aroundpulleys, substantially as herein shown and described.
